British number two Heather Watson reached the semi-finals of the Birmingham Classic with a straight-set victory over third seed Donna Vekic.
The 29-year-old Briton broke Vekic twice in each set and will meet Tunisian second seed Ons Jabeur for a place in the final later on Saturday.
Jabeur, ranked 24th in the world, beat Russian Anastasia Potapova 6-4 6-0.
Watson, who led 5-2 when China's Zhang Shuai retired in their quarter-final match on Wednesday, broke the Vekic serve in the Croat's opening two service games.
The world number 54 restored parity before Watson held on for the first set.
